If tracking names expose information that should not be in URLs, start by preserving one representative example. It gives the investigation a concrete reference and makes the eventual correction easier to judge.
Find the likely cause
Free-text fields contain customer-specific details.
Treat this as an explanation to verify against the actual work. Look at the input, the relevant decision, and the final result together. If the evidence does not support this diagnosis, investigate the mismatch before applying a convenient but unrelated fix.
Make the targeted correction
Use non-sensitive campaign identifiers and review generated links.
Tracking conventions should make campaign sources understandable without creating a different label for every contributor's preference.
Check that the repair worked
Inspect the full URL before it is shared or published.
Repeat the check on the final version that the reader or customer will encounter. An approved draft, a preview, and a published result can differ; the acceptance decision should concern the version people actually use.
Prevent the next related failure
A separate issue to watch for is this: campaign reports split one campaign into many names. Use a shared naming convention and approved link builder.
Monitor the useful outcome
Track unclassified visits, inconsistent labels, and whether campaign records can be reconciled with reports.
Keep a short record of the original symptom, the evidence behind the diagnosis, and the result of the acceptance check. That record makes the solution reusable when the same condition appears again, without assuming that every superficially similar problem has the same cause.
